The direction of depth of section is provided with to be enclosed between a pair of vertical baffles, and the steel pipe column of each vertical baffle and side corresponding to its and sets
Into a connecting cavity, steel plate rib is provided with the connecting cavity.
Described vertical baffle is arranged in the range of ± the 100mm of girder steel height.
The position of described steel plate rib is corresponding with the position of the web of girder steel.
Described steel plate rib is arranged in the range of ± the 100mm of girder steel height.
The thickness of described steel plate rib is identical with the thickness of the post arm of steel pipe column.
The thickness of the post arm of described steel pipe column is 12mm.
The length of described steel plate rib is 50mm.
When the width of girder steel is more than 300mm, one steel plate rib is provided only with described connecting cavity.
Described node is arranged in the range of ± the 150mm of girder steel height.
Described steel pipe column is the steel pipe column of rectangular cross-section.
Described girder steel is i-shape steel beam.
Compared with prior art, in the structure of girder steel of the present invention and steel pipe column rigid joint, due to rectangular steel pipe column dimension
It is smaller, to ensure concreting, vertical baffle is set, it is to avoid the stop of diaphragm plate.Simultaneously because rectangle steel tubing string is provided with steel
Rib of slab, solves the problems, such as that flakiness ratio transfinites, therefore node district locally thickeies post jamb.The node be arranged on girder steel height ±
In the range of 150mm, the post jamb of rectangle steel tubing string is thickeied to 12mm.Locally set perpendicular to reach node rigid connection effect, in the region
To dividing plate and steel plate rib.Due to being not provided with diaphragm plate, concreting has quality assurance.Special joint is designed, it is to avoid tabula
Plate, it is ensured that workability, can effectively reduce steel using amount, cost-effective.Calculated by nodal finite element, node of the present invention is in lotus
Carry in the case of least favorable, deformation still linearly increases node and is in elastic range, in can be widely applied to steel structure system.
